Patent FR-2604994-A1 (FR)
Title: Composite materials with inorganic matrices
Inventor: DAVIDOVITS NICOLAS
IPC: C04B35/80
Filed: 1986-10-14
Abstract: The subject of the invention is the description of composite materials based on short, long or continuous fibres, resistant to temperature, in which the inorganic matrix is a silicoaluminate geopolymeric compound which is the result of a reaction of inorganic polycondensation of reaction mixtures based on alkali metal and/or alkaline-earth metal silicoaluminates. The main subject of this invention is the description of various composite materials in which the inorganic matrix consists of this alkali metal and/or alkaline-earth metal silicoaluminate geopolymeric compound. The inorganic polycondensation is of the hydrothermal type closely related to that which makes it possible to obtain minerals such as synthetic zeolites or feldspathoids, or geopolymers of the poly(sialate) or poly(siloxosialate) type. The reaction mixture is highly alkaline in the presence of concentrated NaOH and KOH. Under these conditions glass fibres are degraded, as is aluminium, which reacts violently, producing a release of hydrogen. To the great surprise of the Applicant Company, it was found that, if an additional reactant component is employed in the alkali metal silicate reaction mixture, in the form of a sulphur compound soluble in the reaction mixture, this sulphur compound not being a sulphate, in order to end up with the formation of a sulphosilicoaluminate geopolymeric compound, this geopolymeric compound obtained according to the invention did not degrade glass fibre and did not react with aluminium despite the pH of the reaction mixture which was close to 14. The addition of the sulphur compound which is soluble in the solution of alkali metal silicate or of alkali metal aluminosilicate protects aluminium and glass fibre against alkaline attack. This surprising phenomenon has not yet been explained.

Patent FR-2605868-A1 (FR)
IPC: G07F7/06
Filed: 1986-10-29
Abstract: The present invention relates to a self-service dispensing device with a return of issued packs, especially for bottles of liquefied petroleum gas having a cap for protecting the tap head, in which two compartments, each forming a location for a bottle, one intended for receiving the empty issued container and the other (4) containing a full container, are equipped, the first with a member detecting the weight and/or shape of the said empty container and the second with a member for retaining the full packaging container, the said retaining member of the second location releasing the container only when the detection member of the first detects the presence of an empty container in this first location. According to the invention, the member (16-24) for detecting the placement of an empty bottle in the first compartment (3) consists of a hook (16) or a similar member for catching the cap of the bottle, which, under the action of the weight of the bottle, raises a collar (23) or other similar member fitting round the cap and above the body of the full bottle located in the second compartment (4). The invention makes it possible to check that the issued pack has been returned safely together with its protective cap.

Title: Internal combustion turbine with endless effect piston
IPC: F01C21/08
Filed: 1987-12-08
Abstract: Improvements made to a rotary internal combustion engine which gives it a turbine behaviour and allows it to be much economical, much smaller, much lighter and nonpolluting. In addition, these improvements mean that the piston of this engine receives a continuous thrust during its entire rotation, and that it is almost as powerful at altitude in a rarer atmosphere as on the ground in an atmosphere of normal density. It is therefore very suitable, due to its smallness, its aerodynamic shape and its low consumption, for propelling flying craft. Here, for example, the engine 1 rotates the compressor of a jet engine and a propeller, which gives it dual propulsion, using a propeller and a jet, and where one can become aware of the smallness of the engine with respect to the propeller, and its aerodynamic nature.
